hello, i am building this
http://www.forsselltech.com/8chsum_2.pdf
(its an 8 channel to 2 channel passive summing bus)
question is if i went to 10 channels (or 16) would i want to keep the resistance at the summing node the same by chaning the resistor values (currently each channel has a 5k hot and 5k cold) or keep them at 5k reguardless of how many channels i add.
i guess i don't know how to think about it... input channels need to see 5k or the output impedence is a function of these 5k parallel resistors.
help
thanks
